HEADLIGHT.

. Application filed January 9, 1926.

This invention relates to improvements in headlights for motor vehicles, my princlpal object being to provide a headlight for this purpose having a light and reflector arrangement of such a nature that a very strong beam of light in the form of a trans verse band will be thrown onto the road ahead of the vehicle without causing any blinding glare. A very good driving light, yet one absolutely safe from the standpoint of other drivers approaching, is therefore provided.

In certain respects the present device is similar to the structure shown in my Patent No. 1,558,570, dated October 27th, 1925, but the construction has been considerably simplified and just as good, if not better, results are now obtained.

These objects I accomplish by means of such structure and relative arrangement of parts as will fully appear by a perusal of the following specification and claims.

In the drawings similar characters of reference indicate corresponding parts in the several views: I

Fig. 1 is a sectional elevation of the headlight.

Fig. 2 is a sectional'plan on the line 22 of Fig. 1.

Referring now more particularly to the characters of reference on the drawings, the numeral 1 denotes the upper casing of the headlight of cylindrical form and with a hinged cover 2on top.

At the front of the casing is a small translucent lens 3 of frosted or opal glass, backed by a reflector 4 of ordinary character, with a low candle power light 5 therein. This is merely a pilot light for the same purpose as described in the above mentioned patent and does not affect the main lighting fea tures hereinafter described.

Mounted in the casing 1 at the bottom thereof and extending over its full area is a downwardly facing reflector 6 of substantially circular form. Centrally mounted in this reflector and slidable through a sleeve 7 fixed thereon is an elongated light socket 8 carrying a light 9 on its inner end. This socket is adjustably fixed on the sleeve by a set screw 10 mounted in said sleeve.

Below the casing 1 but mounted in unitary association therewith is another casing 11. This casing follows the curvature of the casing 1 at the front but its back portion is rectangular and extends rearwardly of the Serial No. 80,158

casing 1 as shown. The front end of the casing 11 may however be also rectangular if desired.

Aportion of the front of the casing 11 is open as at A and is covered by a curved door 12 hinged at one end and provided with a transparent lens 13. Beyond this door one side or the other of the casing has a window 1%, the window being located on that side facing outwardly of the vehicle to whichthe headlight is attached. i

In the bottom of the casing below the level of the door 12 is a flat reflector 15, facing the reflector 6 in concave relation thereto and axially alined therewith, the diameters of the reflectors 6 and 15 at their rims being substantially the same.

Disposed in the casing 11 at the rear of said reflectors is a plurality of transversely alined' and vertically disposed reflectors 16 each with a centrally located light 17 therein. The diameter of these reflectors is practically equal to the spacing between the rims of the reflectors 6 and 15. They are connected together as a unit by upper and lower

horizontal rods

18 and 19. 'The upper rod 18 is hinged ontothe casing, while the lower rod 19 is attached to a threaded stem 20 which extends rearwardly of said rod at right angles thereto. This stem passes through a post 21 projecting upwardly from the bottom of the casing 11, adjusting nuts 22 being placed on'the stem on both sides of the post. This enables the reflectors 16 to be tilted in unison oneway-or the other, which will of course alterthe line of projection of light rays striking the same. A door 23 hinged along its upper edge is mounted on the rear of the casing 11 so that the adjusting nuts 22 can be reached at any time, while being normally roncealed.

A wire 24; from the battery of the car is connect-ed to a standard form of socket 25 mounted in the back of the casing 1, to which socket a wire 26 is connected having branches leading to the sockets of the Va rious lights. Connection with the sockets of the lights 5 and -9 is made by raising the lid 2 while connection with the sockets of the lights 17 is easily made upon opening the door 23. e

A transparent lens in the form of a door 27 concaved relative to the reflector 6 ex tends across the bottom of the same and is hinged at the back of the casing 1 so that it may be lowered from the front end and the light 9 raised when the door 12 is opened. The lens 27 if 'made with the proper curvature relative to the reflectors aids in distrlbuting rays from the reflector 6 to the reflector 16. Vertical adjusting of the light 9 of course also determines the di-' rection of the reflected rays from the reflector 6 toward the reflector 15. i The reflector 6 throwsa flood of light downwardly through the lens 27 and against the reflector 15, which results in a flood of through the front lens 13 from the reflectors 16 of greater intensity than that initially generated by the lights 17 providing a very strong light for driving purposes, and yet one such that no glare will be thrown into the eyes of oncoming drivers; The exact horizontal direction of this beam is of course governed by adjustment of the reflectors 16.

A certain amount of the flood of light within the casing between the various reflectors is of course thrown through the side window 14 to'illuminate the road directly to the side of the vehicle.

From the foregoing description it will be readily seen that I have produced such a device as substantially fulfills the objects of theinvention, as set forthherein.

While this specification sets forth in detail the present and preferred construction of the device, still in practice such deviations from such detail may be resorted to as do not form a departure from the spirit of the invention as defined by the appended claims. I

Having thus described my invention what I claim as new and useful and desire to se- 7 cure by Letters'Patent is: a

1.. A headlight including an opaque casing structure, a downwardly facing reflector therein, a source of light in the reflector, an upwardly facing reflector below the first reflector in alined but spaced relation there- ,to, a vertical reflector at the back of the casing disposed in transverse plane between the other reflectors, the front of the casing having an opening between the first two reflectors, a source of light in said vertical reflector, and means enclosed within the casing for enabling thevertical setting of the last named deflector to be altered at will. i

2. A headlight including. an opaque casing structure, a downwardly facing reflector therein, a source of light in the reflector, an upwardly facing reflector below the first reflector in alined but spaced relation thereto, a plurality of transversely and horizontally alined and vertically disposed reflectors mounted in thecasing to the rear of the first reflectors and disposed in the space therebetween, sources of light in said vertical reflectors, and an openingin the-front of the casing between the first two reflectors.

3. A headlight includingdan opaque casing structure, a downwardly facing reflector therein, a source of light in the reflector, an upwardly facing reflector belowthe first reflector in alined. but spaced relation thereto, a plurality "of transversely and horizontally alined and vertically disposed reflectors mounted in the casing to the rear of the first reflectors and-disposed in the space therebetween, sources of light in said verti cal reflectors, means for mounting the verticalreflectors in hinged relation to thecasing as a unit for swinging movement in a transverse vertical plane, and means applied to the said reflectors for, controlling such movement.. v i V In testimony whereof I aflix my signature I JOHNS.
